Television: Security Is a Good Show

December is the gruelingest month, the
time when there seem to be more seasonal "specials" than
regular shows on TV. But this Thursday (7:30 p.m., E.S.T.), CBS will
carry a special that really is special. For one thing, the pro gram is
unpretentious; for another, it is unprolonged (30 minutes). Finally, it
represents the overdue TV debut of the comic strip Peanuts.
